The AKO-14412 uses a high accuracy (±1°C) NTC thermistor input (1.5M lead sensor included) to monitor temperature, and incorporates 4 relays (3 SPST, 1SPDT) with which to control equipment. The controller is powered via a 12V input and has been designed to fit into a standard 70.5 x 28.5 mm panel cut-out, into which it can fit into using the clips provided. The controller is configured for a monitoring range of -49.9°C to +99.9°C, and the controller itself has an ambient operating temperature of 5°C to 50°C. The controller features an extensive range of programmable parameters for controlling refrigeration, defrosting, fan and alarm functions.
